BIN DI NG-POST FOR ELECTRICAL CONNECTIONS.

SPECIFICATION forming part of Letters Patent No. 503,427, dated August15, 1893.

Application filed March 24, 1893. Serial No. 467,477. (Nc model.)

To @ZZ whom it may concern,.-

Beit known that I, ARNOLD KOHL, of Centralia, in the county of Marionand State of Illinois, have invented a new and Improved Binding-Post forElectrical Connections, of which the following is a specification,reference being had to the annexed drawings, forming a part thereof, inWhich- Figure l is a side sectional elevation of a gas bracket providedwith my improved binding posts. Fig. 2 is an enlarged verticaltransverse section of the binding post. Fig. 3 is an enlarged verticaltransverse section of a double binding post; and Fig. it is an end Viewof a binding screw.

Similar letters of reference indicate corresponding parts in all theviews.

The object of my invention is to provide a simple and effective bindingpost for insertion in gas fixtures, for making connections between thewire contained by the gas fixtures, and the house Wires and burnerWires.

My invention consists in a threaded post perforated by one or morelongitudinal holes, provided with a clamping screw entering the side, acontact screw entering the end, and a binding nut on the contact screw,all as will be hereinafter more fully described.

The body a of the binding post A, is made of insulating material such ashard rubber or vulcanized liber. The body is bored axiallyforasinglewire, as shown in Fig. 2, and is perforated with two or morelongitudinal holes when it is to be used for making connections with twoor more wires. The end of the post which is to be inserted in the gasfixture is provided with an external thread, and the outer end isthreaded internally to receive the contact screw b. The screw b ispreferably threaded throughout its entire length, and upon it is placeda metallic nut c. In the side of the postis inserted a binding screw d.

The insulated wire B, which is to be inserted in the post is stripped ofinsulating material at the end, and its end is received in a hole ebored axially in thelower end of the screw b. The wire B is clamped bythe screw d, and the screw b is turned down into electrical contact withthe stripped end of the wire B. Two such binding posts are necessary forcompleting the circuit through a gas fixture, one being inserted in thefixed end of the fixture, the other being inserted in the end next theburner. The wireB is con veyed through the fixture and is secured at itsends in the binding posts. clamped between the end of the binding postbody A and the metallic nut c, and the Wire leading to the electricalgas lighter is clamped in a similar manner by the nut c ofthe bindingpost adjoining the burner.

The construction of the double binding post shown in Fig. 3, is the sameas that already described, wth the exception of the insertion of two ormore Wires, two or more binding screws and two or more contact screws.This binding post is used where the return current is conveyed by a Wireinstead of the fixture itself.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. An electrical binding post, formed of alongitudinally-bored body, a clamping screw inserted in the side of thebody and adapted to clamp an insulated wire within the binding post, acontact screw inserted in the end of the binding post, and a clampingnut on the contact screw, substantially as specified.

2. An electrical binding post, formed of a body of insulating materialbored axially and provided with a clamping screw, an axially boredcontact screw inserted in the end of the post, and a clamping nut placedon the contact screw, substantially as specified.

3. The combination, with a gas fixture or any pipe, of binding postsinserted in the fixture and provided with clamping and contact screws,substantially as specified.
